Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551764, here are decompositions:

11 + 551753 = 551764
41 + 551723 = 551764
47 + 551717 = 551764
71 + 551693 = 551764
113 + 551651 = 551764
167 + 551597 = 551764
281 + 551483 = 551764
383 + 551381 = 551764

Showing the first eight; more decompositions exist.
